What causes dandruff
Dandruff is a common condition, but that doesn't make it less embarrassing! Let's begin addressing the problem by figuring out the typical causes of dandruff.
You have dry, sensitive skin or allergies. Just like your skin anywhere else in the body, your scalp could be flaking as a sign of irritation, or reaction to certain triggers. It might be an allergic reaction to food, sensitivity to a hair product, or a symptom of a skin condition like eczema or seborrheic dermatitis.
You're not shampooing as often as you should. Another cause of dandruff is having an excessive build-up of the natural oils on your head plus the styling products you use every day. If you don't wash your hair regularly, this heavy build-up of oil, grease, sweat and product residue may cause dandruff flakes to form.
You have oily hair that feeds your scalp fungus. Icky as it sounds, there is a yeastlike fungus called malassezia that's naturally present on everyone's scalp. What causes your dandruff might be oily hair, which the fungus love to feed on. This irritates your scalp, so you shed skin cells faster as a response—all that dead skin is what appears as flakes.
